Hello, I would suggest to replace the two methods -------------------------------------------------------------- OSPRocess class >> platformName "After Squeak version 3.6, #platformName was moved to SmalltalkImage " ^ ((Smalltalk classNamed: 'SmalltalkImage') ifNil: [^ Smalltalk platformName]) current platformName OSPRocess class >> osVersion "After Squeak version 3.6, #osVersion was moved to SmalltalkImage " ^ ((Smalltalk classNamed: 'SmalltalkImage') ifNil: [^ Smalltalk osVersion]) current osVersion -------------------------------------------------------------- by: ------------------------------------------------------------- OSProcess class >> platformName ^ ((Smalltalk classNamed: 'OSPlatform') ifNil: [ (Smalltalk classNamed: 'SmalltalkImage') current ifNil: [^ Smalltalk platformName]]) platformName OSProcess class >> osVersion ^ ((Smalltalk classNamed: 'OSPlatform') ifNil: [ (Smalltalk classNamed: 'SmalltalkImage') current ifNil: [^ Smalltalk osVersion]]) osVersion ------------------------------------------------------------ to avoid deprecation messages when using it in Pharo 1.2. Does it looks good? I'm not able to publish on the squeaksource repository
